The Futurist magazine has a fair share of green technology predictions. In the article below it discusses future buildings being designed to be responsive to fluctuations in the surrounding climate in hopes to increase their resource efficiency. The technology is referred to as “Protocell cladding” which takes advantage of bioluminescent bacteria or other such materials by using them as coatings for the outside of building structures. These materials will be designed to collect water and sunlight, helping to cool the interiors and produce biofuels.
Coincidentally, another article in the futurist predicts the destruction of the worlds resources as the East becomes more materialistic like the West. Perhaps the green movement will reverse this trend by making our materials less "damaging" to the ecosystem. I guess I know which prediction I'll be rooting for.
